sPHENIX discussion of the superconducting solenoid

["Yip, Kin" <kinyip AT bnl.gov>]

Hi,

Thanks Paul for the message.  The cool-down has finally started (for more 
than an hour already) !

I've just logged to the HMI and taken a snapshot (as attached).   There is 
right now a ~31K difference in the temperature
gradient.  The lowest (valid) temperature seems about ~227 K but many still 
show 296 K.  Due to my ignorance, I 
wonder whether they are just slower in the circulation sequence or the 
thermometers are faulty :-)
